Inspired by glamour, these Womens Bifocal Sunglasses have it all going on. In a blush frame with gold detailing you will look stylish whilst being practical. The bifocal lens section at the bottom of the glass gives you magnified vision to your choice of strength whilst the rest of the lens remains unmagnified for your distance viewing. Gradient lenses are tinted from the top down, so that the top of the lens is darkest. These lenses are good for reading, because they shield your eyes from overhead sunlight and allow more light through the bottom half of the lens so you can see your text clearly.
You must wear sunglasses to prevent damage to your eyes. While some contact lenses provide UV protection, they don’t cover your whole eye, so you still need sunglasses. Cat 2 lenses are the most common category to be found in sunglasses, for general use they provide good protection from visible light and from UV rays. This lens will have a tint which allows through less light than category 1 but more light than category 3
When do UV rays affect my eyes?
Most people think that they’re at risk only when they’re outside on a sunny day, but UV light can go right through clouds, so it doesn’t matter if the sky is overcast. The sun’s rays are strongest between 10 am and 2 pm.
Glare and reflections can give you trouble, so have your sunglasses ready if you’ll be around snow, water or sand, or if you’ll be driving (windshields are a big glare source).
The following put you at additional risk: sunlamps, tanning beds and parlors, photo sensitizing drugs and living at high altitudes or near the equator.
